Posterior Column of the Spinal Cord

The posterior column of the spinal cord (columna dorsalis) is the part of the spinal cord that is located at the back of the spine and is responsible for controlling the movements of the muscles of the back and torso. The posterior column consists of several sections, each of which performs its own function.

The first section is the motor center, which controls the movement of the muscles of the trunk and back. It receives signals from the brain and transmits them through the spinal cord to the muscles.

The second section is the center responsible for the sensitivity of the skin on the back and buttocks. It receives information from skin receptors and transmits it to the brain.

The third department is the coordination center, which is responsible for coordinating movements and maintaining body balance. It receives information about the position of the body and transmits it to the brain.

The posterior column of the spinal cord is also involved in regulating body temperature, respiration and heart rate.

Overall, the posterior column of the spinal cord is an important organ that provides control over movement and sensation in the body, and also plays an important role in motor coordination and balance.

Posterior Column of the Spinal Cord

Introduction

The posterior column of the spinal cord (fasciculus longitudinalis medialis) is one of seven (there are six in humans) columns of the spinal cord, which starts from the medulla oblongata and runs along the entire spinal trunk to the sacrum. It belongs to the group of medial (lateral) pathways and is the main structural element in the conduction system of the spinal cord. Although the dorsal column is the best known column of the spinal cord due to its connection to the cerebellum, it also has important functions in transmitting information to many other parts of the nervous system.

Description of the Posterior Column The posterior column includes not only the brain itself, but also the nerve fibers that connect it to other parts of the nervous system, including the cerebellum, medulla oblongata, pons, and spinal cord. This facilitates the transmission of nerve impulses between different parts of the nervous system to coordinate movements.

A collection of neurons called the thoracic nucleus is found in the transverse flexor (striated muscle), located deep in the dorsal trunk. About 20 percent of the fibers of this nucleus, which is located in the posterior column and is small in size, provides automuscular connection with the back
